> In MLX5_IB_METHOD_STEERING_ANCHOR_CREATE, the user-supplied u16 priority
> is passed directly to _get_flow_table() without an upper bound check.
> This can lead to out-of-bounds array accesses on dev->flow_db priority
> tables.
>
> Check that priority does not exceed MLX5_IB_FLOW_LAST_PRIO before calling
> _get_flow_table(), matching the existing validation in raw_fs_rule_add()
> and mlx5_ib_create_flow().
